(A) Cellulose, the other major polysaccharide of glucose found in plants, serves a structural rather than a nutritional role. It is an unbranched polymer of glucose residues joined by β-1,4 linkages.

(B) Dextrans are mainly composed of α1→6-linked glucose residues that display a variable degree of branching at position 3 (resulting in α1→3-linked branches) and less frequently at positions 2 and 4, resulting in α1→2-linked and α1→4-linked branches, respectively.

(C) Chitin is a linear homopolysaccharide composed of N-acetylglucosamine residues.

(D) Glycogen is a polymer of α(1→4) gly...
